Article abstract of DOI:10.1039/c39810000937

The synthesis of cis-1R2)2> is reported, and its geometry, inferred from 31P n.m.r. data, is confirmed by X-ray crystallography for R1 = R2 = Me; when R1 <*> R2 racemic and meso-diastereomers are formed in varying ratio consistent with asymmetric induction during stepwise chelation to give the rac-complex as the preferred isomer, and this is proven where R1 = Me, R2 = Ph by diastereomer separation followed by Pt-Si bond-cleavage with (+)-EtCH(Me)CH2I.
